Germany plans to dim lights at night to save insects

Habitat loss is a key factor, probably the key factor, but the reasearch around artifical night light and fireflies/glowworms goes way beyond 'recall more than they were kids' - not sure why you'd pick that as main argument from a Wikipedia page. See e.g. https://www.researchgate.net/publication/339213788_A_Global_... page 4 and beyond which reads

  Observational and experimental studies provide evidence hat ALAN adversely affects firefly populations. Several studies have shown negative correlations between high levels of ALAN and firefly abundance.

and mentions several studies regarding the subject (though also warns it's hard to pinpoint the main cause amongst the variety of other negative factors).

I was specifically responding to the Wikipedia extract.

The citation for the statement "Firefly populations are declining worldwide, for a variety of reasons" is a link to firefly.org. That is a small, Texas group that appreciates Fireflies, which is nice. But it is home to no studies, no research, no analysis. Nor does it (that group, or the wiki page that was cited to apparently refute my personal anecdote...) cite the publication you mention. So I'm not really sure what we're discussing here.

I'm not disagreeing that there is a decline for a multitude of reasons, or that light is probably bad, but if someone says "my yard has no fireflies the apocalypse is upon us" it probably isn't credible.
